|June 2, 2012
Summary
New visualization techniques, including recurrence plots (RPs) and fuzzy symbolic dynamics (FSD) plots, aid in understanding complex neurodynamical systems. These methods reveal insights into attractor basins and neural network dynamics, with implications for cognitive disorders.
Area of Science:
- Neuroscience
- Computational Neuroscience
- Cognitive Science
Background:
- Analyzing complex neurodynamical systems is challenging.
- High-dimensional trajectories and phase space dynamics require advanced visualization tools.
- Understanding attractor basin relationships is crucial for system analysis.
Purpose of the Study:
- Introduce novel plotting techniques for visualizing high-dimensional neurodynamical systems.
- Enhance the understanding of phase space, attractor basins, and neural network dynamics.
- Investigate the neurodynamics of a semantic layer model of dyslexia.
Main Methods:
- Developed and utilized color recurrence plots (RPs) to display inter-point distances in trajectories.
- Employed fuzzy symbolic dynamics (FSD) plots to map trajectories into 2D or 3D using fuzzy membership functions.
- Analyzed the variance of trajectories within attraction basins against synaptic noise variance.
- Visualized distances between trajectory points and reference points, such as attractor basin centers.
- Simulated and analyzed the activity of 140 neurons in a dyslexia model using the Emergent neural simulator.
Main Results:
- RPs and FSD plots effectively visualize global phase space and attractor basin relationships.
- Trajectory variance plotted against synaptic noise variance provides insights into basin size and shape.
- Analysis of a dyslexia model revealed complex neurodynamical aspects of lexical concept activation.
- Neural accommodation parameters significantly influence trajectory dwell times.
Conclusions:
- Novel visualization techniques offer powerful tools for analyzing complex neurodynamical systems.
- The study provides insights into the cognitive neurodynamics of lexical concept activation.
- Variations in neural accommodation parameters may correlate with attention deficit disorders like autism and ADHD.

01:18Functions of the Nervous System
The nervous system is responsible for coordinating and regulating the body's functions. It functions through three main processes: sensory, integrative, and motor processes. Sensory function involves the detection and transmission of information about internal and external stimuli from sensory receptors to the CNS. The CNS processes this information through an integrative function, where it interprets and makes decisions based on the incoming sensory information. Finally, the motor function...
01:25Neural Circuits
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

01:26Autonomic Nervous System: Overview
The human nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord, while the PNS contains nerve cells, clusters of nerve cells, and the sensory receptors that are outside the CNS. The PNS has two types of nerve cells: sensory (afferent) and motor (efferent). Sensory cells send signals to the CNS from receptors, and motor cells carry signals from the CNS to organs, muscles, and...

01:13Organization of the Nervous System
The nervous system is one of the most complex systems in our body. It is organized into two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS, comprising the brain and spinal cord, houses billions of neurons. The brain is housed in the skull, while the spinal cord is linked to the brain through the foramen magnum of the occipital bone and is surrounded by the protective structure of the vertebral column. It is responsible for processing various...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
